Add:

* Use UTF8 encoding for NLS messages so all server encodings can
read them properly

< o %Add support for Unicode
<
< To fix this, the data needs to be converted to/from UTF16/UTF8
< so the Win32 wcscoll() can be used, and perhaps other functions
< like towupper(). However, UTF8 already works with normal
< locales but provides no ordering or character set classes.
